Abstract:
<div>Stainless steel production typically follows the duplex process, beginning with the electric arc furnace (EAF) and proceeding to the vacuum oxygen decarburizer (VOD) or argon oxygen decarburizer (AOD). The EAF's role is to melt the charge and heat it up for further processing, reducing tap-to-tap times through partial oxidation. [..]

Abstract:
<div>In the iron and steel industry large amounts of fine granular bulk material like iron ore fines, fluxes, foundry sands or residues from off-gas dedusting have to be handled. In storage, conveying and handling of such materials wall friction between the particles and the wall material is an important parameter. [..]

Abstract:
<div>Nowadays, steelmaking companies use numerical simulations as an advanced tool to optimize process parameters, reduce defects, and enhance product quality, aligning with the rising market demand for high-quality steel ingots. For more accurate simulations, it is essential to set the correct material properties, process parameters (such as flow rate and temperatures), heat transfer coefficient, as well as the suitable geometry and corresponding discretization.

Abstract:
<div>The submitted contribution is focused on the mathematical determination of temperature and thermal parameters depending on the heat removal from solidifying steel in the mould, respectively in the primary zone during continuous casting of steel. The main task of primary cooling is primarily the heat dissipation from solidifying steel, therefore the knowledge of temperature fields in the billet and mould is important. [..]

Abstract:
In numerical process design, the heat transfer coefficient (HTC) is used to calculate the intensity of heat transfer at an interface, for example between dies and workpiece. In most finite element calculations for bulk metal forging, a constant HTC is currently assumed, as there is no complete understanding of the relationship between the heat transfer coefficient and its influencing variables (e.g. [..]

Abstract:
<div>The paper is focused on experimental research with the goal of enhancing cold mill capability by improving the currently used coolant setting (various types of emulsions) and cooling configuration (type of nozzle, nozzle position, distance and inclination angle of headers with respect to the roll).The experimental research was divided into two phases. The initial phase examined the impact of various emulsion types on cooling intensity. [..]

Abstract:
<div>Designing processes for producing responsible structural elements from steel in the hot forging process requires knowledge of the relationship between the process parameters, the microstructure that is formed under the assumed deformation conditions as well as the quality and properties of the forgings. The analysis of the microstructure after deformation allows the identification of phenomena occurring during hot processing, such as work hardening, recovery and recrystallization. [..]

Abstract:
<div>The article concerns preliminary research involving the development of a flow model for a material consisting of a mixture of clay (70 %), quartz sand (10 %) and ceramic flour (20 %) in an upsetting test in order to determine the course of plasticizing stress as a function of actual strain. This material constitutes the mass for the production of ceramic roof tiles and, at the beginning of the process, it is pressed through forming tools, then cut to the appropriate size, stamped and dried.
